High humidity issue

[robb]

Hi Maestro

I've just bought a classical guitar, solid spruce top and solid rosewood side/back. The thing is after i brought it home the guitar changed, the action became higher, sound softer, tone dead. I suspect it is due to high humidity, the humidity in my home is about 70%.

I was wondering is it possible for you to setup the guitar to play in this high humidity condition?
